OK, here's the story.
I have a 1303 s super beetle with a 1600 engine.
It had a 009 distributor and it ran fine, BUT following the motto "If it ain't broken, you can still try to improve it" I exchanged the 009 for the SVDA distributor.
Reajusted timing to 7,5 before tdc, and reajusted the carb to the specs in my manual.
But now when running idle for about 15 seconds the idle drops from 1000 rpm to something like 500 rpm, and after that it will struggle and die.
Also when I have to stop for traffic lights and I'm going from
80 km/h to zero the rpm drop to 500 also, but this could be the same thing as described when running at idle at standstill.I checked the vacuum, it moves the breaker points plate and it retains it's vacuum.
What's wrong, do I have to do my reajustments again? I find it strange that it runs relatively fine at idle for a while and then falls back in rpm, quite suddenly.
Any suggestions?
Greetings, Gerrelt
